I found that using low firrtl can pass the compilation. Now my project can run with essent.

Yes!

Unfortunately, it might take us 3 weeks to get to FIRRTL 1.3.2 support, but that is next on our list.

Amazing! I am looking forward to the new version! :)

We support at least FIRRTL 1.3.1. Does that help?

It works!

But when I try with another project using FIRRTL 1.4.0, essent (commit c062973) still reports error. I upload the fir file here. The error says:

Exception in thread "main" scala.MatchError: WSubAccess(WRef(bankHitWays,VectorType(UIntType(IntWidth(1)),16),WireKind,SourceFlow),WSubIndex(WRef(bankIdxInOrder,VectorType(UIntType(IntWidth(4)),16),WireKind,SourceFlow),0,UIntType(IntWidth(4)),SourceFlow),UIntType(IntWidth(1)),SourceFlow) (of class firrtl.WSubAccess)

We now support 1.4.3. Hopeuflly we will be quicker to support 1.5.0 when it is released.
